Abstract

Laser-like mechanoluminescence is reported in the spintronicmaterial ZnMnTe. The luminescence was also observed when the material was exposed to UV and x-rays. Photoluminescence spectra consisted of peaks at 386.5 and 648 nm, which may be attributed to band gap, and levels, respectively. Lattice contraction, sharpness of the x-ray diffraction peak, and the blueshift in the energy gap confirm the nanostructure of the material. A possible mechanism for lasing is also suggested.
